Stanish (2003: 21) expands on Polanyi's system by describing political economy in the prehispanic Andes with deferred reciprocity taking the form of competitive feasting and political support (Hayden 1995;Stanish 2003: 21). Stanish observes that while there was an implicit or explicit (Service 1975) evolutionary sequence going from reciprocity to redistribution and finally to markets, more recent evidence suggests that these modes can co-occur and that the relationships are too complex to collapse into a single sequence.
